Abstract

Improvements in the provisions of insurance for fusible cartridges, specifically for the types of high and medium voltage, characterized because in parallel with a bundle of main fuse conductors, intended to conduct almost all the current until its fusion happens, there is another conduit more resistant composed of two elements in series and of different characteristics, the first of which has a melting time constant much greater than the second, the latter serving as a means for the mechanical retention of an alarm indicator hammer, so that it offers greater resistance to traction, so that when the main conductors merge, the current passes through the secondary conductor, then melting the second element of this conductor, releasing the said hammer, then melting the first element of the conductor. Own driver to be closed the circuit under the small isolation there is an existing arc between said element and the mass of the cartridge, where an arc is produced, finally achieving the necessary isolation between the poles of the cartridge.
